This mobile phone footage shows a 17-year-old engaging in a 'friendly street fight' moments before he died, possibly of injuries sustained in the scrap.

Police are now studying the film in the hope that it could provide answers.

Nabeel Mohammed was wrestling in the street with a group of friends in Hyderabad, India, when another young man is said to have delivered a series of punishing blows to his head, stomach and kidneys.

In the footage, Nabeel is seen collapsing to the floor as pals gather around him.

His friends are reported to have taken Nabeel to hospital, where he was pronounced dead, before it is alleged they returned his lifeless body to his family home, claiming he had lost his life in a motorcycle accident.

Six of the teenagers are now in custody, while the male directly involved in the fight, Owais Mohammed Patel, is on the run, according to the Indian Express.

Suspicion over Nabeel's death was raised after his father arrived home from working in Saudi Arabia and found Nabeel's friends had different accounts of the incident.

He added: "The fight was between Nabeel and Owais and the friends waged bets and took sides.

"They also gave advice to both of them on how to fight to win. There are many things that raise suspicion, like the timing of the match.

"In the video, one person is seen whispering in Owais's ear just before the bout started. What did he tell him? Was it only for betting or were Nabeel and Owais involved in a feud and this was organised to settle it? We are investigating all this."

Inspector Seetharamulu explained that most of the young people had destroyed the memory cards in their phones, but police managed to trace one video of the incident.
